Makary’s nomination came as part of a string of health leadership announcements that Trump made on social media yesterday. Trump also wants Dr. Dave Weldon, a former Republican congressman from Florida, to be the next Centers for Disease Control and Prevention director, and Fox News contributor Dr. Janette Nesheiwat to be U.S. surgeon general.

Makary himself has appeared as a commentator on Fox News and contributed opinion pieces to The Wall Street Journal and Washington Post. He’s also authored bestselling books on healthcare reform, including “The Price We Pay,” “Unaccountable,” and the recently published “Blind Spots: When Medicine Gets It Wrong, and What It Means for Our Health.”

A member of the elite National Academy of Medicine, Makary also has a reputation for bucking the status quo. For example, he questioned broad vaccine mandates as the COVID-19 pandemic wore on, though he was an early proponent of lockdowns and universal masking.
